P009

She works on smart metering (hardware and software) to improve communication between the meter and computer to the millisecond

Pretest

Ranking appliance by use

10 minute limit was not clear

Anything with heating and cooling uses a lot

Dryer & washer use energy in a concentrated amount of time

Rank by cost

Add monthly to the title

Initially, not clear to her that it was different compared to the last question

Had to point out that it was asking for monthly

Considers frequency of use

Refrigerator runs all the time

Oven used infrequently

Compare by use

Freezer keeps things at a lower temperature

Microwave heats more than the fridge cools

Dryer has a higher heat

Compare by monthly cost

On all the time -- freezer

Doesn't see difference in use from 10 min to 1 month for the items presented (except for last one)

Microwave vs fridge (fridge was chosen cause its on all the time)

Elec cost

When demand is high, it is more expensive to provide

Elec use

Answered with similar reasoning from previous questions

Cost of kWh / Monthly kWh

No clue at all

Make question text bold

Ranking energy saving actions

AC consumes the most -- largest saving potential

Heating uses the second most

Water heating uses the third most

Washing energy use comes mostly from mechanical energy, so not much savings

IHD Simulation

kWh & $ by appliance

Is this fora month's usage

This isn't the first time the time frame the simulation was considering. If we create a scenario where we tell them input numbers for a week of use, they can put things into context.

Or we can make give participants learning strategies or goals to try to guide them

Her strategy was:

Run everything for an hour

Revisited the ranking questions by pointing out which appliances used the most

Asked whether this page was just for viewing? Was it made to estimate the bill for the house?

Remove text in intro about $150 bill

Elec knowledge questions

Switch off the AC because it costs $0.6 / hour

I suggest we give them input numbers for average use per week. that way they have an understanding of how the Smith's consume electricity and have guidance in constructing effective strategies to reduce the bill by $10

Post test

Cost by monthly

Add the text "average summer month"

Cost of kWh

Add the title to the page

Used info from energy saving suggestions question

$10, 75 kWh

General suggestions

Do the simulation for a one day usage so they could ahve more context

Summer vs winter day

Weekend vs weekday

Simulate maximum the bill could possibly go up to

Order appliances as you input variables on the simulation

Maybe think about including a pie graph or visual graph of usage by appliance

reduce cost by $10 by turning off appliances from a default setting on the simulations

Feedback info

Does total kWh & cost mean just the total and no other appliances?

Maybe make it so you can choose multiple answers instead of a single answer
